cgroup: add seq_file forward declaration for struct cftype
Recent header file changes for cgroup caused lots of warnings
about a missing struct seq_file form declaration for every
inclusion of include/linux/cgroup-defs.h.
As some files are built with -Werror, this leads to build
failure like:
from /git/arm-soc/drivers/gpu/drm/tilcdc/tilcdc_crtc.c:18:
/git/arm-soc/include/linux/cgroup-defs.h:354:25: error: 'struct seq_file' declared inside parameter list [-Werror]
cc1: all warnings being treated as errors
make[6]: *** [drivers/gpu/drm/tilcdc/tilcdc_crtc.o] Error 1
This patch adds the declaration, which resolves both the
warnings and the drm failure.
tj: Moved it where other type declarations are.
